The player, Maliki Mills, did play in the Terry Sanford playoff game on Saturday.
The North Carolina Athletic Association said it is challenging the court's decision.
In court Monday, coaches, administrators and the Terry Sanford Booster Club thought the hearing over a player's eligibility would be about whether he attended enough classes to be eligible. But they were blindsided with accusations that Mills got credit for two classes -Business Law and Weightlifting- which he never attended.
During the hearing, it was revealed that a school resource officer tipped off the "head office" to the alleged grade tampering.
Officials say the student in question allegedly got "A's" for classes he never attended and a "F" in English that was allegedly changed to a "C". There were also suspensions that were supposedly "expunged."
The teachers say they don't know how that happened and his English teacher said in a written affidavit that he deserved the "F".
"No they were not tampered with," Mill's mother Ethel Johnson said. "There's more to the story ? it will all come out in the wash."
It is unknown what role ex-principal Diane Antolak played in the controversy. Last week, Cumberland County Schools appointed a replacement for the suspended principal.
There is still no decision on whether the school will be able to continue in the state football playoffs. The hearing will continue Tuesday.
If Terry Sanford is ruled ineligible, the season will be over and the team's next opponent will get a bye.
